Subject: Re: [PATCH RT 2/2] fix printk flush of messages
Date: Wed, 16 May 2012 18:17:26 -0700 [thread overview]
Message-ID: <4FB451A6.4030306@am.sony.com> (raw)
In-Reply-To: <4FB44FD0.4090800@am.sony.com>
The patches were tested on an ARM panda board for linux-3.4-rc5-rt6.
The panda board has a compile error in linux-3.4-rc5, which is fixed
by commit 13176a89e1c4a0011bd9f576730b0338ecb619ff in linux-3.4-rc6.
Without the patch, the printk() output from the following commands
does not appear on the console, until flushed by 'echo >/dev/console'
echo h >/proc/sysrq-trigger
echo p >/proc/sysrq-trigger
echo m >/proc/sysrq-trigger
With the patch, the output flushes to the console immediately.
